PokeyMAX - FPGA replacement

Probably you saw it earlier. There is a nice FPGA project. Currently only pokey is implemented but also planed are more sound chips implementation: $D20x: 1 POKEY $D21x: 2 POKEY $D22x: 3 POKEY $D23x: 4 POKEY $D240..$D25F: 1 SID $D260..$D27F: 2 SID $D280..$D283: COVOX $D284..$D285: 1 PSG $D286..$D287...
